The most difficult gun for me was a shotgun. I had been trained pretty well for most of my life on rifles, but I never owned a shotgun and never learned to shoot one well.
It usually a punishing experience with no training, as I was young at the time, and I never used one very much at all. When I did, it was someone else's and varied from a 410 to a 12 gauge with no time on any one of them. I cannot hit anything with them in spite of shooting clay pigeons with a .22 when I was young.
I am not afraid to use one, but my ability is much better with rifles and pistols than shotguns. I have never had the urge to buy one for this reason.
